Switzerland: The Science-Based Targets Initiative (SBTi) has validated Holcim’s 2050 net zero CO2 emissions pathway. The pathway consists of targets covering Holcim’s entire value chain, across Scopes 1 – 3.
CEO Jan Jenisch said “The building sector has an essential role to play to accelerate our world’s transition to net zero. I am proud to be joining the SBTi today to announce Holcim’s net zero pathway to 2050. By setting the first Net-Zero Standard for our industry, we are walking the talk on our commitment to take science-driven action to win the Race to net Zero.”
Switzerland: Jura Cement has installed a PREMAS 4.0 continuous monitoring system supplied by Aumund at its Wildegg cement plant. The system informs operators about the condition of the equipment used in cement production at the plant in real time via the PREMAS Cloud. It also provides service life estimates for critical components.
The Wildegg plant previously hosted a prototype PREMAS 4.0 in early 2020.
Head of Maintenance Ramona Keller said “We are convinced that predictive maintenance has a future. With PREMAS 4.0, we can better plan spare parts and maintenance, which has a positive effect on resources and costs. The PREMAS Portal is easy to use and very clear. It enables us to recognise immediately where there is a need for action, regardless of time and place."

Holcim launches 2030 People Strategy
26 October 2021Switzerland: Holcim has announced new global social impact targets for 2030 under its new People Strategy. The targets fall under three pillars. These are ‘bridging the housing and infrastructure gap,’ ‘improving livelihoods’ and ‘upholding human rights.’ The company says that this will entail efforts to ensure adequate housing and infrastructure for all, support for health, education and skill building and the implementation of due diligence across its value chain. The strategy includes a target to create Euro468m of social value by 2030. The figure will include the total value of schools, hospitals, rural roads and affordable housing renovated or built in the period. Between 2016 and 2020, Holcim benefited over 31m people with Euro187.21m in social investment.
CEO Jan Jenisch said “Our business plays an essential role in society's progress. We build the roads, bridges, hospitals and schools that enable people to thrive around the world. With 3bn people expected to lack access to adequate housing by 2030, I am committed to putting our business to work to uplift our communities.”
Holcim to reduce water intensity of cement production by 33% before 2030
08 September 2021Switzerland: Holcim has announced further details of its ‘nature-positive’ 2030 biodiversity and water management strategy. The producer says that under the strategy it will implement a 33% reduction in its cement operations’ water intensity by 2030. It will reduce the water intensity of its ready-mix concrete operations by 15% over the same period. Across all its activities, it is aiming to achieve water positivity at 75% of its sites and install a water recycling system at every site. The company says that it will continue to develop and deploy its nature-based approach across its products and solutions.
Holcim sets 2030 biodiversity and water targets
03 September 2021Switzerland: Holcim has announced a strategy to become ‘nature-positive’ by restoring and preserving biodiversity and water. It will also undertake measures to bring more nature into cities. The strategy is based on transformative rehabilitation plans and measured by a science-based methodology developed in partnership with the International Union for Conservation of Nature (IUCN). Holcim aims to replenish freshwater in water-risk areas while lowering water intensity across all its product lines. It will also accelerate the deployment of solutions such as Hydromedia and green roof systems for more liveable urban environments. The group says that its nature-positive strategy places it among the top 1% of the 500 largest global companies with science-driven biodiversity targets.
Chief Sustainability and Innovation Officer Magali Anderson said, “With nature at the heart of everything we do, I am pleased that we are taking significant steps to improve our biodiversity and water stewardship in a measurable and science-driven way. Building on our Net Zero commitment, our nature-based solutions play a vital role in reducing the impact of climate change and increasing our business resilience. Becoming nature-positive plays a critical role in our vision to build progress for people and the planet.”
Drone usage by the cement industry
25 August 2021Holcim Schweiz hit a milestone recently with the aerial drone programme at its Siggenthal cement plant. The project with Voliro, a Switzerland-based technology start-up, has started to use multi-rotor drones to conduct official measurement flights. They used them to take measurements to determine the steel wall thicknesses of the cement kiln and the cyclone preheater. The work has been part of Holcim’s ‘Plants of Tomorrow’ industrial automation plan with unmanned aerial vehicles (UAV). Key features of the particular drones being used are that they can be rotated around all axes by a special rotor system and can even fly upside down.
Holcim has been using drones in and around cement plants for a few years now. When it launched the Plants of Tomorrow plan in 2019, Switzerland-based drone supplier Flyability said that the cement company had chosen its Elios 2 model to perform confined space inspection. Earlier in 2017 another supplier, SenseFly, said that LafargeHolcim Tanzania had been using its fixed-wing products. Holcim is also far from alone in its use of drones. A few examples among many include Cemex USA’s work with Kespry earlier in 2021, HeidelbergCement’s work in North America and Germany in 2020 and 2021 and Votorantim’s testing at its Córdoba and Niebla plants in Spain back in late 2015.
UAV usage by armed forces dates back to examples like unmanned incendiary balloons being deployed in the 19th century to Azerbaijan’s reported decisive use of drones in its war against Armenia in late 2020. The current era of industrial UAVs began after 2000 when governments starting issuing civilian permits, miniaturisation occurred and improvements in cameras, sensors and computing power followed. For the mineral processing sector the trend started with drones being used for stockpile management and quarry surveying. At present this is the main area that UAVs are used for by the sector, often coupled with photogrammetry techniques. CalPortland’s Adam Chapman’s paper at the 2021 IEEE-IAS/PCA Virtual Cement Conference described one company’s use of UAVs in the cement industry since 2016, looking at licensing, cost, quality of data, drone technology, fleet management and field experiences.
More recently though, tests of drones used to survey cement plant buildings and structures have started being publicised such as Holcim’s work at Siggenthal. A presentation by consultant John Kline and Chris Place of Exelon Clearsight summarised the use of drones for structural inspection at cement plants at the Global CemProducer 3 webinar in January 2021. The key benefits they promoted of using an UAV in this way were: improved safety because workers have reduced risk from climbing, working at height or in confined spaces; less time to conduct a survey; higher resolution photographs and video; better coverage through grid method surveying; and an overall lower cost. However, on that last point, other commentators have noted that market-leading drones for surveying are relatively expensive and easy to damage. Drones have since been used to start going inside structures at cement plants with Kline demonstrating their use to inspect the condition of refractory within the cooler, kiln, pre-heater and cyclone of a production line at the Global CemProducer 2 webinar in July 2020. HeidelbergCement has also been doing similar things, with an inspection trial using a drone of the kiln at the Schelklingen plant in Germany during the 2021 maintenance shutdown period at the site.
So far the use of drones by the cement industry has mostly been in a surveying or inspection capacity. Given the short time that UAVs have been used like this there is likely to be scope for lots more development both within existing fields and new ones as the sector works out how best the technology can be used. One application we couldn’t find in the research for this short article was the use of drones for security and surveillance tasks at cement plants and quarries although this may be happening already. However, there could be a more active role for drones if or when a company finds a way for them to start making basic repairs or carrying out simple maintenance in those hard to reach areas that drones excel at accessing. Research examples exist of UAVs being used to spray concrete or repair materials onto minor defects in concrete structures. Yet considerable challenges face these kinds of applications such as the weight of a loaded multi-rotor drone or damage from rebound. Before we all get too worried about drones replacing our jobs though it is worth considering that Amazon’s plan to deliver packages by UAV was first announced in 2013 and it still hasn’t happened yet. It may yet, but for now in most situations humans remain cheaper and more practical than robots or drones.

24 August 2021Nigeria: Lafarge Africa has ranked first on PWR Advisory’s Nigerian Exchange Top 20 companies for gender diversity. 46% of the group’s board seats are female-occupied, up from 40% in 2020.
Chair Adebode Adefioye said “Lafarge Africa's commitment to female representation at the board and management rank and file level is unwavering. Our diversity and inclusion targets, which align with our sustainability strategy, set us apart and are a clear indication of our resolve to continue on this trajectory for more extraordinary outcomes. We remain resolutely committed.”
Lafarge Canada supplies EcoPact Zero concrete in Canada
24 August 2021Canada: Lafarge Canada has supplied the first EcoPact Zero near-zero net CO2 ready-mix concrete in Canada. The subsidiary of Switzerland-based Holcim supplied the concrete to a Habitat for Humanity housing development site in Kingston, Ontario.
Switzerland: Holcim’s sales rose by 17.4% year-on-year to Euro11.7bn in the first half of 2021 from Euro9.92bn in the same period in 2020. Its recurring earnings interest before taxation (EBIT) increased by 66% to Euro1.84bn from Euro1.12bn. Cement and concrete sales volumes grew by 13.5% to 99Mt and 15.6% to 22.1Mm3 respectively. Sales of all business segments grew in all regions on a like-for-like basis with the exception of aggregate sales in North America, where they fell slightly.
Jan Jenisch, the chief executive officer of Holcim, said, “In the first half of 2021 we set new records in recurring EBIT, free cash flow and earnings per share.”The group’s acquisition of Firestone Building Products officially closed at the end of March 2021 and the company has also made seven ‘bolt-on’ acquisitions so far in 2021, mainly in aggregate and ready-mixed concrete markets in Europe and North America. The group also agreed to divest operations in Zambia, Malawi and the Indian Ocean in the reporting period and these are all expected to complete by the end of 2021.
Low carbon cements go global
28 July 2021Holcim has started to unify its low carbon cement product range this week with the launch of its ECOPlanet label globally. The products are already available in Germany, Romania, Canada, Switzerland, Spain, France and Italy. The plan is to extend this to 15 countries by the end of 2021 and then to double its ‘market presence’ by the end of 2022.
The headline news is that the range will include what Holcim says is the world’s first cement product with 20% recycled construction and demolition waste. This appears to be an improvement on the group’s Susteno cement products that use fine fractions from concrete and demolition waste. This product is currently sold in Switzerland where it is advertised as saving 10% of CO2 emissions compared to a standard cement product. Both Holcim and HeidelbergCement already sell concrete products that use the coarse waste from building demolition. Other than this, Holcim says that the range will also include cements that contain calcined clay. In June 2021 subsidiary Lafarge France announced that it would produce a cement product under the ECOPlanet banner using kaolin clay with its proprietary ProximA Tech process at its integrated La Malle cement plant in Bouc-Bel-Air.
We will have to wait and see how far Holcim goes in standardisng the range between different countries. Yet, judging from what the countries that are already selling ECOPlanet are doing, it looks like it will be a variety of blended cements. At present, for example, Holcim Germany offers four products in the ECOPlanet range. These are all slag cements, with three having effective CO2 reductions of up to 70% and the fourth, ECOPlanet Zero, reaching 100% through a carbon offsetting scheme in conjunction with MoorFutures. Holcim Italy also launched a product in the range called ECOPlanet Prime using calcined clay in June 2021.
Incidentally, LafargeHolcim US announced a research project this week with the US Army about using demolition waste. It’s going to start working with the US Army Corps of Engineers’ Engineer Research and Development Center and Geocycle to look at how construction and demolition materials from military installations can be used for energy recovery and mineral recycling. Group resources at Geocycle’s Holly Hill Research Center in South Carolina, US and Holcim’s Global Innovation Center in Lyon, France will be used in the scheme.
Other low carbon cement products are available of course. Holcim is far from alone in launching low CO2 cement and concrete products. Yet the use of worldwide brand names is different. Cemex is doing something similar with the global rollout of its Vertua concrete products. It first launched Vertua in France in 2018 before going global in 2020. Holcim started to launch ECOPact Concrete in 2019. Now, Holcim has gone further by doing the same thing with cement. Given how localised cement and concrete products are, it will be instructive to see how global branding for low carbon cementitious products helps these companies. For instance, who is the target audience? It could be eco-minded self-build customers or project specifiers or government departments or industry lobbyists. Or perhaps it is simply another marketing channel to reinforce the sector’s sustainable offerings.
The other point worth considering is when will the multinational cement producers start selling sustainable cements and concretes in less rich parts of the world? While Holcim was playing with blended cements and marketing this week, Dangote Cement said that it was ready to start commissioning its new 6Mt/yr integrated plant at Okpella, Edo State in Nigeria. Another 5Mt/yr plant is also on the way in the country from Madugu Cement. It has just signed a contract for China-based Sinoma International Engineering Company to build it. When Holcim and the other cement companies start selling low carbon cements in places like Nigeria then the rise of these products will be complete.
